Devices
CPUs
Use -cpu [type][,...] to use a given CPU type. Common ones are listed below.
| Type | OS | Description |
|---|---|---|
| host | Various | The Host CPU. If KVM is enabled, this will clone your host's CPU ID and flags to the VM. |
| max | Various | The Host CPU. If KVM is enabled, this will clone your host's CPU ID and flags, and also enable every possible subfeature. However, unlike host, this CPU type also works with TCG, and allows emulating the max feature set TCG supports (with your QEMU version). |
